Open the CIPO recordAbstract From the Canadian patent
The present invention provides a method for presentation of multiple disease associated antigens in antigen-presenting cells which can be used to generate a prophylactic or therapeutic immune response against the disease with which the antigens are associated. The method employs differential screening of nucleic acid sequences expressed by target and non-target cells. By identifying nucleic acid sequences preferentially expressed in a target cell population and expressing the identified sequences in antigen-presenting cells, one can stimulate an immune response directed at a target cell population without being limited to single previously identified antigens.

Why it's free to use
- Filed August 10, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 10, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 10, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
